\nThe correct answer is (B) Stigma, Style, Ovary.
\n<\/section>\n
\nIn the typical process of fertilization in flowering plants, a pollen grain lands on the stigma (the receptive tip of the pistil\/gynoecium). If compatible, the pollen grain germinates and grows a pollen tube. This pollen tube grows down through the style (the stalk connecting the stigma to the ovary) and eventually reaches the ovary, where it enters an ovule to deliver the male gametes. Thus, the correct sequence of the pollen tube pathway is Stigma -> Style -> Ovary.
\n<\/section>\n
\nThe pistil or carpel is the entire female reproductive part of a flower, typically consisting of the stigma, style, and ovary. Starting the sequence with “Pistil” is not detailing the pathway *through* the parts of the gynoecium.
